HEAT EXCHANGE ELEMENT EFFICIENCY IMPROVEMENT METHOD Russian patent published in 2015 - IPC F28D7/02 F28F13/08 

FIELD: power engineering.

SUBSTANCE: invention relates to heat exchange devices and can be used in power engineering and related industries. The method consists in heat exchange intensification by means of implementation of periodic ring ledges on internal surface of the heat exchange element. The heat exchange element is designed as a helicoid flexible pipe with the turbulisers which are periodically located on its internal surface, preferably, as a ring ledges, meanwhile the radius of the spiral R is made within 0.05≤D/R≤0.25, where D - the pipe internal diameter, R - the spiral radius, the internal diameter d of ledges - within 0.85≤d/D≤0.98, and the step between them - within 0.45≤t/D≤0.6.

EFFECT: improvement of efficiency of heat exchange element.
